Fabric Technology for Comfort, Functionality and Peace of Mind

The founders of Knixwear say that their products replace the need for panty liners, which both saves you money and helps the environment. Their panties are designed for women with active lifestyles and are a response to an underwear market they believed had too many frills and not enough functionality.

Knixwear is the result of careful thought put into performance, design and technology combined to produce attractive, comfortable, functional and fashionable intimates.

 

 

How Do They Work?

Knixwear period underwear uses moisture-wicking fabrics with 100 percent cotton gussets for absorbability. You have the choice of adding a leak-proof lining to each of the period panty styles described below. Keep in mind that will raise the price of the undies by two to five dollars per pair.

Special Features

The leak-proof lining is designed to be a backup to your menstrual cup, pad or tampon during your period. The lining is Knixwear’s own patented technology called Fresh Fix Technology; it’s absorbent, leak-resistant and odor eliminating and took them two years to develop and test to perfection. They state that their cotton top layer dries two times faster than regular cotton.

Fresh Fix Technology

The Fresh Fix Technology in Knixwear’s period panties is a panty liner that’s built-in. It has properties that are moisture-wicking, leak-proof and it absorbs up to three teaspoons of liquid. This technology is built into the fabric and is designed to last. The gusset or crotch area of the panties with Fresh Fix Technology will be about 2mm thick.

Knixwear is made to be machine washed in cold water and laid flat to dry. They have 10 different styles.

About the Company

Knixwear is a high-tech brand of women’s underwear that’s headquartered in Toronto, Canada. Their products are designed by women with other women’s needs in mind. They launched in 2013 thanks to a successful crowdfunding campaign. Their goal is to make the lives of women a little bit easier every day.

 

 

 

The Bottom Line

Knixwear leak proof underwear are extremely comfortable and high-quality undergarments. Customers agree that they all have excellent moisture-wicking qualities. The Fresh Fix Technology actually works to keep moisture away from the skin and prevent leaks. The sizing is right and the designs are attractive especially the lace fabric panties.

The main complaint from customers seems to be that you can’t return Knixwear panties. If you were planning to buy a few styles and sizes to try on with the intention to returning the ones you don’t want for a refund, think again. Knixwear will in some cases work with you to make an exchange, but they will not issue a refund for a return.

When it comes to buying clothing, having the option to return items for a refund if needed offers a lot of peace of mind, so that’s the main strike against this brand.

    Just tried these recently. They suck, they’re not even period panties in no way, just an expensive underwear. The only plus side is they don’t ride down. I leaked within 10 minutes.

    + PROS: Stay in place
    - CONS: No absorbency, bled through in 10 minutes.
